When marketing a recurring event, you might want to share specific info with your customers about a certain occurrence, for example, if one occurrence has particularly low availability.
To do this:
Head to 'Events'
Click on the recurring event you want to update.
Select 'Occurrences' from the left-hand menu
Select the occurrence you want to edit from the list.
In the floating menu, select 'Set available'.
Add the message you want to show to your customers at checkout, e.g. "low availability" (or anything else!).
